I know there isn't a simple answer but is there anything besides medication that might help to reduce the effects of OCD? Like I have really embarrassing habits that I do and at school it's hard to hide them. I don't know if someone has already posted something like this, but does anyone have any advice?

One way I've managed to cope with the majority of my compulsions is to use some sort of negative reinforcement.
While I can't say it works for everyone, my friend swears electroshock therapy works. Personally I just used the classic rubber and technique.
Or a different look is to take time and positively point out to your self when you succeed in resisting an impulse. It's all mostly finding what works for you. Good luck.
